### What's IFR departure procedure from private field with encroaching obstacles but no published ODP?

TL;DR: There are no instrument procedures into 26MA, so there are no instrument procedures out of it either. Proceed with extreme caution. Departure in non-VFR conditions is not recommended. As @...

### If an Airport has only a VCOA and a SID, does the VCOA count as an ODP, and if not, does that mean you can fly a diverse departure?

Edited based on new information… I communicated with both the procedure designer for Gray AAF and with the FAA’s Flight Standards office. There are 2 answers for this question: First, the VCOA at Gray ...

### How much clearance is provided when taking off over a 50 foot obstacle?

Calculated figures for take-off distance required (TODR) are to only just clear a 50-foot obstacle at that distance (with gear down), and figures provided by aerodromes for take-off distance available ...

### What's IFR departure procedure from private field with encroaching obstacles but no published ODP?

You really need to question whether departing in IMC from an airport with lots of obstacles is a good idea. But it could be completely feasible: IMC doesn't mean zero visibility. Let's say the bases ...

### During an LPV or GLS final approach, can the extension of the aircraft's cross-section line intersect with the Y or X OCS surfaces?

The OCS is the edge of the safe flight 'corridor.' It defines a safe volume of airspace for the approach. Since it's normal to have obstacles off to the side of the approach path the OCS typically ...

### EOSID - Adhere to at or soon after V1?

V1 should be calculated based on the actual conditions, so if you have an unbalanced field available, that's what it should be calculated from. The V1 speed itself has zero effect on obstacle ...

### What is the difference between MOCA and OCA?

Closely reading the definitions in the OP, the MOCA exists with reference to a defined segment, while the OCA or OCH exists with reference to a specified runway threshold or a specified aerodrome. ...

### How should this ODP be flown at KELP?

In instrument flight, when a Radial is given, it is always the “From” indicated radial on your OBS. In vectoring, turning an aircraft at acute angles is avoided. Flying a Heading of 120° to intercept ...

### A Question about Departure Procedures at KLRU

The only takeoff departure at Las Crucas, NM (KLRU) is a visual climb over airfield (VCOA). Typically you would depart the airport and visually see and avoid the obstacles around the airport while ...

### How much clearance is provided when taking off over a 50 foot obstacle?

The answer is provided in FAR Part 23. There is no conservatism involved. The distance provided is what the airplane can do. §23.2115 Takeoff performance. (b) For single engine airplanes and levels ...

### What are early/inside and late/outside turns (see, e.g., PBN Manual Order 8260.58A) and when do pilots perform them?

I think what you're talking about are what pilots refer to as "fly-past" and "fly-over" waypoints. Up until recently, all waypoints in the world were "fly-past", ie you could cut the corner from one ...

### How to accurately determine Navigation Accuracy from FAA's PBN Criteria (Order 8260.58A)?

Im more familiar with EASA then FAA but im sure there are similarities: why a desired ground track would require a smaller navigation accuracy value? RNP 2: the aircraft must be within ± 2 nm of ...

### Why does obstacle clearance area splay outward instead of being a rectangle?

Because the navigational beacons and the indicator instruments in the cockpit are such that the system is less precise at longer distances. Second the plane must find the initial fix or intersection ...
